The numeral 8 indicates as an entirety the chassis of a folding babycarriage disclosed and broadly claimed in the application heretoforeidentified with the exception of the .side bars 9 and folding bodysupports 10 at the ends of said chassis.

Referring now in detail to the present invention the numeral 11indicates a collapsible flexible body made from any suitable materialheld to form by upper and lower tubular Divided and this applicationfiled Serial No. 405,116.

metallic frame members 12 and 13, respectively, the former of which hason its under side and the latter of which has on its inner sidelongitudinal slots 14 and 15, respectively. Each frame member 12 and 13and its slots 14 and 15, respectively, is in endless arrangement and theends of said members are connected, as will hereinafter appear.

The body 11 is attached to the frame member 12 by having its upper edgeportion, which extends through the slot 14, folded around a iiexiblecore 16 in said member and secured thereto by stitches or otherfastening means 17. The frame member 18 is secured to the lower edgeportion of the body 11, which extends into said body through its slot15, by a flexible core 18, similar'to the core 16, and which core 18 issecured to the body 11 by fastening means 19 similar to the fasteningmeans 17.

A flexible apron 20 forming a depending extension of the body 11 isstitched or otherwise attached to said body, at the frame member 13, andsaid apron at its lower edge is attached to a tubular metallic framemember 21 of substantially the horizontal contour as the frame member 13and has in its inner side a longitudinal slot 22. The connection betweenthe apron 20 and frame member 21 is, as shown, the same as that of thebody 11 and frame member 12, wherein the lower edge portion of the apron20, which extends into the framemember 21 through its slot 22, is foldedaround a flexible core 23 in said member 21 and is secured thereto bystitches or other fastening means 24.

Preferably each frame member 1213 and 21 is formed from two duplicatemetallic tube sections of such gauge as to keep their form under theload they must sustain but at the same time having such flexibility asto produce an easy riding body. The ends of these tube sections formingeach framemember 12-13 and 21 are rigidly connected by coupling sleevesor other fastening means 25 that do not obstruct the slots 14, 15 and 21in the respective frame members 12-13 and 21. Manila rope or othersimilar material may be used in forming the cores 16-18 and 23. In theconstruction of the improved body the cores 16-18 and 23 are firstthreaded end- Wise into the sections of the respective frame memberswhich are primarily straight and thereafter bent to form. The couplingsleeves are then applied to the abuttlng ends of the sections of theframe members 12-13 and 21 and secured thereto by rivets.

' apron 20ers suspencl'ediroin the framevmeiw ber 12 and the framemembers 13 and '21 hold said body and apron taut. From the abovedescription it is evident that eaehfrarne anember'1'2'13 and 21 and eachcore 16, 1 8 and 23 is, in 'a broad sense-endless.

' .Y Vithinth bod 11 is an inclined back support 26 of fabric or other'fiexible material andvthe "lower edge portion btwhich is sewed orotherwise'se'cured to the bottom of said body; rearward of thelongitudinal center thereof. A strap 27' is sewed to the upper edge.portion of'theback support '26 and has onits ends hooks '28 adapted tobeinsertv ed through any one pair of transversely aligned longitudinallyspaced holes 29 formed in the top of the frame member 12 '(see Figs. 4and 5) Obviously, by adjusting V the hooks'28'in different transverselyaligned pairs of holes 29 the inclination of the back support 26 may bevaried at will. 1 Byre'leasing the hooks '28'from the frame member 12the back support 26 may be laid flat on the bottom. of the body 11 andunder the bedding :therein; v e.

Said apertur ed plates 30are detachably secured tothebody support 10 bybeing remov-' ably applied to upstandinggheaded studs '31 on said bodysupports. The springs 32 which extend horizontally and transversely ofthe body :11 have their intermediate por I tions secured to said platesby folding said plates therearound and theirfends are anchored by slortboltsto outwardlyand down- 'wardly projecting lugs 33 formed with thecoupling sleeves 25 for the sections of the frame member 12.

A pair of stabilizers are provided for'cus hments of the body 11inrespect to the chassis 8. -As shown there is one of these stabilizerseachjsid-e of the body 11 and each thereof 7 7 comprises a coil spring34 intermediately and detachably secured by a hook-like clip 35 to therespective side of the frame member 21 at the longitudinal centerthereof. The end portions of the springs 34 are in diverging relation inrespect to the clips 35 and have their ends secured at 36'to theunderlying side bars 9. See Fig. 1). By reference to Fig. 3 it will benotedthat the clip 35 is attached tothe frame member 21 bybeing hookedthereover.

therefor. The above desoribed'bo'dy when not in usemay'be folded intocompact form and is "of lightweight. i WhatI cl'aimis: e

'1. A'eoll'apsible body of the class described having an upper marginalframe member, and a flexible"intermediate backmember attached at itsloweredg'e in respect to the body and having at its upper edgea pair ofhooks adapted to be inserted through any one 1i air v 'of a 7multiplicity of longitudinally spaced h'o'lfe'sinltheframe member for"detachabl'y securingtheback memberto the frame member at differentjlongitudinallyspaced points to vary the inclination of the back member.

"'2. neollapsibjlebocly of the'cl'a'ss described having on its bottom adepending endless flexible apron which extends completely around thebody, and'an endless frame member extending completely around the bottom'of the 'apron and supported entirely thereby with freedom to permit thefapronfto be-co'llapsed with thebodyresti n g'on the frame "member.

A c'o'llapsiblebody of the "class describ d having on itsbottom adepending flexible 'ap'ron which extends completely around the body, atubular frame member "extending completely aroundfthe bottom of theapron "and having 1a; continuous longitudinal slot, and a core in theframe member to whichthe apron is attached throughthefslot; V

4. The combination witha chassis, of a collapsible body suspended from"the fchassis and having on itsbottomfa dependingfiexible apron which.extends completely aroundthe body, 'a frame member-extending completelying means connecting the 'fr'a'm'e m je'mber to "the chassis and holdingthe flexible apron taut. v

- 5. iThe conbination with a chassishaving a pair of substantiallyparallel side members, of a collapsible body, means suspending the bodyfrom the chassis, said body having at its bottom a depending flexibleapron which extends completely around the body, a frame member extendingcompletely around the bottom of the apron and suspended entirelytherefrom, and a coiled spring on each side of the chassis attached atits ends to the respective side member of the chassis and attached atits intermediate portion to the respective side of the frame member.

6. A collapsible body of the class described having a continuous tubularframe member provided with a continuous longitudinal slot, and a core insaid member, the sides and ends of the body being continuous andattached at their upper edge portions through said slot to the core.

7. The structure defined in claim 6 in which the frame member compriseshalf sections connected by couplings.

8. The structure defined in claim 6 in which the frame member compriseshalf sections connected by couplings, the joints between the halfsections being at the ends of the body, and which structure furtherincludes body suspending means attached to the couplings.

9. A collapsible body of the class described having a frame comprisingupper and lower tubular members, each of said members being continuousand having a continuous longitudinal slot, and a core in each of saidmembers, the sides and ends of the body being continuous and havingtheir upper and lower edge portions attached through the slots to thecores in the upper and lower frame members, respectively.
